BlueShadow 40D UV/VIS Detector

https://store.knauer.net/web/image/product.template/62954/image_1920?unique=4d55455

without Flow Cell, Test Cell and Accessories included, 190-750 nm

The KNAUER BlueShadow 40D UV/VIS Detector is a competitively priced HPLC spectrophotometer for routine HPLC applications, including fast LC methods. It is equipped with a deuterium lamp that covers a wavelength range from 190 to 750 nm. This robust detector not only offers excellent technical specifications but also features a highly flexible and compact design.

The smart design ensures that the flow cell is easily accessible and can be changed very quickly. Users can choose from a wide range of flow cells with either bio-inert or stainless-steel wetted parts, suitable for nearly any analytical and preparative LC applications, with flow rates ranging from 10 μl/min to 10 l/min.

The BlueShadow 40D can be operated using ClarityChrom®, and OpenLAB® software, or through its integrated display and keypad for stand-alone operation. It supports communication via LAN, RS-232, or through analog input/output, allowing for seamless integration into almost any LC system.
